bottom side and end walls and is open at the top when the device is arranged as illustrated in Figs. 1 and 2 of the drawing. The side walls are preferably tapered longitudinally and the blade holder formed by the bars Vi B and the rods i i and tne group of blades are arranged in the casing with the blades projecting beyond the casing. The blade holder is secured in the casing by screws IG which pierce the side walls of the casing and the adjacent blade clamping bars, as clearly illustrated in Fig; 3 of the drawing. The inner ends of the screws are threaded` into the openings l'! of the adjacent blade clamping bars and in order to enable the holder to fit snugly within the substantially rectangular casing of the frame member l the side walls of the frame member are provided at their inner faces with recesses I8 preferably formed by offsetting portions of the side walls of the casing, as clearly illustrated in Fig. 3 of the drawing. The recesses IS are arranged to receive the nuts Iii andthe terminal portions of the fastening devices H. This provides a compact structure.

Two of the blade clamping'bars of the blade holder are provided with rearward extensions I9 located at opposite sides of thedevice and form- .ing supports for a transverse pivot or pintle 2t to which the guard member is hinged Vor pivoted.

The pintle pierces the spaced extensions il) and the pivoted member 'I is provided at its inner or rear edge withA a transverse flange 2l to which is secured a plate 22 provided with spaced eyes 23 through which passes the pintle 23 whereby the pivoted member 'i is hinged to the blade holder, as clearly illustrated in Fig. 4 of the drawing.v 'Ihe plate 22 constitutes a hinge leaf and the eyes 23 are located at the ends of the plate. The rearward extensions form hinge eyes and the said eyes and the pintle constitute a hinge connection between the pivoted member 7 and the blade holder. l Y

The plater22 is also provided with a centrally arranged rearwardly extending lug 24 extending .through a slot 25 in the flange 2l and connected by links 2S to the front arm` of the operating lever .4. Suitable pivots 2'1V and 28 connect the links 26 tothe lever and to the lug 24. A coiled spring 29 is mounted on the pintle 20 centrally thereof and the terminals 30 and 3| Vof the coil of the spring are extended and bear against the plate 22and the blade holder for holding the pivoted member 'I normally spaced from the blades to form a guard. The end 32 of the terminal portion 33 of the coiled spring is fitted in a socket 33 in one ofthe blade 'clamping barsl and is retained in engagement with the socket by the resiliency .of the spring whereby the spring is prevented from sliding along the pintle.

In the operation of the device the handles 3 and 6 are graspedby` the operator and are compressed by the hand and moved towards each other, the inward movement of the handle 6 with respect to the'handle 3 operating through the AlinksZS to move the pivoted member 'I inwardly towards the blades 8. The pivoted memberis provided with spaced slots 34 through which the cutting edges of the blades project when the piv- Oted member is moved to the limit of its inward The front corner portions Y of the blades are exposed and are eiTective for scoring and tendering the meat and the pivoted member which is curved slightly in a direction longituv 'dinally of the device presents a smooth slightly curved surface to the meat andthe blades will :Tout Vthe surface of. the meat and score .the same to the desired depth severing the ber and rendering the meat tender and easily masticated and digested. As soon as the handle 6 of the lever is released or relieved of pressure the spring 29 will automatically lift or move the pivoted member and carry the same to a position beyond the cutting edges of the blades and it normally covers the blades and forms an eiiective guard for preventing a person from coming in contact with the blades. Also the outward-movement of the pivoted member 1 automatically cleans the blades and removes from the blades any meat adhering to the same after the scoring and tendering operation has been completed.

As the front end portions of the blades are exposed and are the effective portions of the blades in the scoring and tendering operation the eiiective portion of the blades may be readily renewed by simply reversing the blades when the front end portions of the same become dull or worn. The blades are readily removable and may be either sharpened or replaced by new blades when worn or dull. y l l 'Ihe inward movement of the pivoted member 1 is limited to vary the amount of the projecting portions of the blades to adjust the device to score or cut to the desned depth by means of an adjustable stop 35 consisting of an approximately L-shaped plate pivoted by a screw .33 or other suitable fastening device to the inner face of the front wall of the casing V2 and extending upwardly beyond `the upper edge ci the front wall, when the device is in the position illustrated in Figs, 1 and 2 of the drawing, to form a stop for the pivoted member 1. The L-shaped plate extends forwardly to form a iinger piece 31, by means of which the pivoted stop may be readily adjusted and in order to increase the range of adjustment of the stop the front wall is provided with a substantially arcuate slot 38 to receive the forwardly projecting portion of the plate and permit the stop to be swung downwardly to a positionrin flush relation with the upper edge of the front wall of the casing to provide a maximum amount of projection of the blades. The stop 35 is secured in its adjustment by means of a knurled nut 3S arranged on the outer threaded portion of the screw 38 and adapted to be screwed tightly against the front wall of the casing to secure the stop in any position within its range of movement.
